CLAMPING DEVICE.

T all whomit may concern;

Be it known that LJnssIE D. DUDLEY, a citizen .of the United States, residing at Barry, in the county of Pike and State of Illinois, have invented new and useful 1m: provements in Clamping Devices, of which the following is a specification.

The present invention relates to clamp ng devices for wire fences, or the like, and resides 1n the construction, combmationand arrangement of parts set forth in the folpractice, the same, however, being susceptible to such changes as fall within the scope of the claim.

In the said drawings: Figure 1 is a perspective view illustrating the improvement in applied position upon a fence, Fig. 2 is a central vertical sectional view through the same, Fig. 3 is a similar sectional view but taken upon an enlarged scale, Fig. 4: is a sectional view on the line l4= of Fig. 3, Fig. 5 is a similar sectional view on the line 5-5 of Fig. 3, Fig. 6 is a detail enlarged ele-.

structure illustratedin Fig. 7, Fig. 10 is. a

rear elevation of the locking clamp, and Fig. 11 is a perspective view of the same.

The clamp includes essentially an inner elongated substantiallyrectangular plate 1 and a similar outer plate2. The plate 1 is provided at suitable spaced intervals with right angularly arranged adj ustable elements in the nature of headed screws 3. The plate 1 is preferably formed of wood, and has embedded in its inner facea series of nuts 1 which lie flush with the inner face of the plate, the screws 3 engaging thethreads of the said nuts and passingthrough openings in the plate and having their projecting ends also provided with locking nuts 5 which bind against the outer face of the said platej Specification of Letters Patent.

ings 6, corresponding in number with the screws 3, the said openings beingiofa sufficient area to permit the headof the screws passing therethrough and. projecting over the outer face of the said plate 2.. The plate 2, at a suitable; distance from each ofits openings 6, is provided with an outwardly extending stud 7, the said stud being arranged in a line with the center of the openings. It is, of course, to be understood that the plate 1 is to bearranged upon one ofthesides of the wire fence, the plate 2 being arranged upon the opposite side of the wire fence, the screws 3 projecting through the mesh of the wire.

cause the same to exert a pressure upon the vide lockingclamps 8. Each of these clamps includes substantially rectangular. body 9 which is provided with a key-hole opening 10, and is formed with a depression or channel 11 belowthe saidjkey-hole opening, the channel communicating with what Iwill term the lower end of the clamp. The body has its upper end centrally bifurcated for the reception of the cam head 12 of a lever 13, the said head being pivoted to the body, as at 14. Secured upon the under face of the body above its key-hole opening 10 and arranged tobe contacted by the cam head 12 is a fiat spring plate 15 which serves as gmeans for preventing the cam head 12 making indentations or depressions in the plates when the cam is. forced against the plate as will now be described. The body 8 is arranged upon the outer plate 2 permitting.

the head of the screw 3 first passing through the enlarged opening in the key-hole slot to bring the shank of the screw within the reduced opening of the key-hole slot, the head of the said screw being arrangedupon the outer face of the body or upon the outer angular edges provided between the side the channeled portion 11 over the stud 7 securing the locking clamp against lateral movement. The lever 13 is then operated to force its cam head 12 against the fiat plate 15, effectively lockingthe clamp 8 upon the device as well as forcingthe members 1 and 2 into ti ht frictional contact to bind the mesh of the fence therebetween.

. To quickly connect the platesin order to wire fence between the said plates,I pro 10. The body is then moved longitudinally walls provided by the said reduced slot and the face of the body. This movement forces 1. The outer plate 2 is provided withopen- From the above description, takenin connection Wltll the accompanying drawings, the simplicity of the device as Well as the advantages thereof Will, it is thought, be

member having a stud arranged adjacent its opening, a locking clamp, said clamp including a body having a key-hole slot whereby the same may be passed over and brought into engagement With the head of the adjustable member, the body having a channel to receive the stud, the body being further provided with a pivoted cam lever, a flat spring plate arranged upon the body and adapted to be engaged by the cam lever when the same is sWung to secure the looking clamp upon the second mentioned plate.

In testimony whereof I affix my signature in presence of tWo Witnesses.
